The study mainly improved the manufacturing process on satellite imagery drafting with Six Sigma of DMAIC Using satellite ortho image the correction according to the basic principle and the method, it explores the vital factors of manufacturing process capability and finds out the optimal parameters with the Taguchi's method. The study finds that the Cpk obviously increased from 0.47 to 2.42 after using Six Sigma. That means the process capabilities is obviously promoted. The quality accuracy decreased from 2.58 meters to below 1.60 meters, and the variance is decreased. From the empirical point of view, the study improved the manufacturing process obviously.
